Abstract: La présente invention concerne un composite polymère constitué d'un mélange polymérisé de nanotubes de carbone fonctionnalisés et d'un monomère qui réagit chimiquement avec les nanotubes fonctionnalisés. Pour fonctionnaliser ces nanotubes de carbone, on les fait réagir avec un milieu chimique oxydant ou autrement actif, par réactions chimiques ou adsorption physique. Les carbones superficiels des nanotubes ayant réagi sont alors fonctionnalisés avec des fragments chimiques qui réagissent avec les carbones superficiels et des monomères sélectionnés. Les nanotubes fonctionnalisés sont d'abord dispersés dans un milieu approprié tel que l'eau, un alcool ou un monomère liquéfié, puis le mélange est polymérisé. La polymérisation donne des chaînes de polymères de masse croissante liées aux carbones superficiels des nanotubes. Le composite peut être constitué de certaines chaînes polymères incluses dans le composite sans tenir aux nanotubes. Le composite obtenu donne des résultats chimiques, physiques et électriques supérieurs à ceux des composites polymères qui ne sont que physiquement mélangés et ne présentent pas de liaison avec les carbones superficiels des nanotubes.

Abstract: A collar (500) for injecting fluid, such as a formation treating fluid, into a wellbore, and a method for using same. The collar is disposed between the upper and lower packing elements (40, 41) of a pack-off system during the treatment of an area of interest within a wellbore. The collar first comprises an inner mandrel (550) running essentially the length of the collar. The inner bore of the collar is in fluid communication with the annular region between the collar and the surrounding perforated casing by a set of actuation ports (552). A second set of ports (554), known as frac ports, is disposed within the mandrel. In accordance with one aspect of the invention, the collar further comprises a tubular case which substantially seals the frac ports in a first position, and slidably moves along the outer surface of the mandrel in order to expose the frac ports in a second position. In operation, the upper and lower packing elements are set at a first fluid pressure level. Upon application of a second greater fluid pressure level, the upper and lower packing elements are further separated in accordance with a designed stroke length, thereby exposing the frac ports.

Abstract: A grating assembly drive means is connected to control the movement of the movable grating between OPEN and CLOSED positions relative to a fixed grating. The drive means moves the movable grating through yieldable connection when moving toward CLOSED position, whereby when such movement is blocked by a foreign object the movable grating stops without damaging the object or the drive. On the other hand movement by the drive means toward OPEN position is direct after removal of any slack caused by a previous yielding.
